Sotera Wireless develops the ViSi Mobile Patient Monitoring System, a comprehensive platform designed for continuous vital signs surveillance. This system provides constant, real-time data on core vital signs, including blood pressure and heart rate, enabling clinicians to remain connected to their patients. The technology focuses on a new generation of monitoring capabilities, moving beyond intermittent checks to provide a more complete clinical picture.
The company emerged from an understanding that existing patient monitoring solutions often lacked the continuous oversight necessary for optimal patient safety in general care settings. This insight spurred the development of a system that could deliver persistent, high-fidelity vital sign data, addressing a critical need for enhanced surveillance outside of intensive care units. The emphasis was placed on creating a solution that could integrate seamlessly into hospital workflows while providing reliable data.
The ViSi Mobile system is utilized by clinicians monitoring patients across various general care environments, aiming to enhance patient safety through proactive rather than reactive care. Sotera Wireless’s long-term vision centers on transforming patient surveillance, ensuring that healthcare providers have the continuous data needed to anticipate changes in patient condition. The company strives to elevate the standard of care by making advanced, continuous monitoring accessible and effective.

Sotera Wireless (now operating as Sotera Digital Health or Sotera, Inc.) is a medical device company developing the ViSi Mobile System, a continuous vital signs monitoring platform for acute care settings like hospitals.[1][2][4] It serves healthcare professionals and patients in general care units, addressing the problem of undetected patient deterioration between spot checks by providing real-time, cuffless tracking of key vitals—blood pressure, heart rate, oxygen saturation (SpO2), respiration, ECG, posture, arrhythmias, pulse rate, skin temperature, and fall detection—using body-worn sensors that integrate with electronic medical records (EMR).[4][5] The system leverages machine learning from over 22 million hours of patient data to minimize false alarms, enhance workflows, and enable early interventions for conditions like sepsis, improving outcomes in understaffed environments.[2][4][5]
Founded in 2004 and based in Carlsbad/San Diego, California (formerly Triage Wireless), Sotera aims to disrupt traditional spot-check monitoring by establishing continuous surveillance as the new standard, with a mission to save lives through data-driven innovation while prioritizing clinician productivity and patient safety.[1][2]
Sotera Wireless originated in 2004 as Triage Wireless in San Diego, California, evolving into its current form as a Carlsbad-based digital health leader focused on patient monitoring.[1][2] The company emerged from a need to advance vital signs technology beyond intermittent checks, drawing on expertise in sensors, algorithms, and clinical workflows; its name derives from the Greek "Soteria," meaning "savior," reflecting its life-saving intent.[2] Key team members include leaders in patient monitoring tech and clinicians experienced in hospital integration challenges, driving pivotal advancements like the ViSi Mobile System.[2] Early traction built on comprehensive monitoring innovations, with recent milestones including a 2025 U.S. patent grant for optical sensors in vital sign monitoring (applied 2023), underscoring ongoing R&D momentum.[1]
Sotera rides the wave of digital health transformation in acute care, where rising patient acuity, staffing shortages, and demands for remote/continuous monitoring amplify needs post-COVID.[4] Timing aligns with regulatory pushes for better general ward surveillance (e.g., addressing in-hospital cardiac arrest precursors identified in studies like Schein et al., 1990), as spot checks miss rapid deteriorations.[4] Market forces like EMR adoption, AI-driven predictive analytics, and value-based care favor Sotera's scalable, low-burden system, positioning it against competitors in medtech (e.g., similar to GlySure or Biowatch but focused on comprehensive mobility).[1] It influences the ecosystem by pioneering "surveillance monitoring as standard," potentially reducing complications like sepsis/renal failure and enabling enterprise-wide safety improvements.[2][4]
Sotera's trajectory points to expanded adoption in U.S. hospitals, with FDA-cleared expansions, deeper AI refinements from growing datasets, and partnerships for global reach amid aging populations and chronic disease surges.[1][2][4] Trends like interoperable health tech and regulatory emphasis on alarm safety will propel its influence, evolving it from niche innovator to core infrastructure in proactive care. As the original "savior" in vital monitoring, Sotera stands poised to redefine patient safety standards, directly connecting clinicians to lives saved through persistent vigilance.[2]
Sotera Wireless has raised $79.0M across 5 funding rounds. Most recently, it raised $21.0M Venture Round in April 2014.
